! 67: # For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
! 68: # $ac_aux_dir to '$srcdir/foo'. In other projects, it is set to
! 69: # '$srcdir', '$srcdir/..', or '$srcdir/../..'.
! 70: #
! 71: # Of course, Automake must honor this variable whenever it calls a
! 72: # tool from the auxiliary directory. The problem is that $srcdir (and
! 73: # therefore $ac_aux_dir as well) can be either absolute or relative,
! 74: # depending on how configure is run. This is pretty annoying, since
! 75: # it makes $ac_aux_dir quite unusable in subdirectories: in the top
! 76: # source directory, any form will work fine, but in subdirectories a
! 77: # relative path needs to be adjusted first.
! 78: #
! 79: # $ac_aux_dir/missing
! 80: # fails when called from a subdirectory if $ac_aux_dir is relative
! 81: # $top_srcdir/$ac_aux_dir/missing
! 82: # fails if $ac_aux_dir is absolute,
! 83: # fails when called from a subdirectory in a VPATH build with
! 84: # a relative $ac_aux_dir
! 85: #
! 86: # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
! 87: # are both prefixed by $srcdir. In an in-source build this is usually
! 88: # harmless because $srcdir is '.', but things will broke when you
! 89: # start a VPATH build or use an absolute $srcdir.
! 90: #
! 91: # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
! 92: # iff we strip the leading $srcdir from $ac_aux_dir. That would be:
! 93: # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
! 94: # and then we would define $MISSING as
! 95: # MISSING="\${SHELL} $am_aux_dir/missing"
! 96: # This will work as long as MISSING is not called from configure, because
! 97: # unfortunately $(top_srcdir) has no meaning in configure.
! 98: # However there are other variables, like CC, which are often used in
! 99: # configure, and could therefore not use this "fixed" $ac_aux_dir.
! 100: #
! 101: # Another solution, used here, is to always expand $ac_aux_dir to an
! 102: # absolute PATH. The drawback is that using absolute paths prevent a
! 103: # configured tree to be moved without reconfiguration.
